    Any pointers to how to perform the unlocking of bootloader and Magisk install ?

    Recently moved from Moto X4 to Samsung A52 5G.
    This will erase your phone's data so backup first
    This will trip knox and prevent alot of samsung apps working

    Unlocking Bootloader
    1. Enable OEM unlocking in developer options
    2. Turn phone off
    3. Plug a usb into pc but not phone
    4. Hold vol up and down and plug usb into phone
    5. Wait for green screen and follow instructions to unlock bootloader (as follows)
    5.5. Long press vol up on green screen then press vol up again
    Installing magisk
    1. Download your firmware from the internet
    2. Extract the AP tar.md5 file
    3. Place file on root of phone
    4. Download and install Magisk (I used Canary)
    5. Make sure connected to internet
    6. Open Magisk and press the top install (Manager not the app install)
    7. Select Install > Select and Patch a File and select the AP file you put on the phone
    8. Wait for it to patch and create a new file
    9. Find the new file, usually called magisk_patched in your downloads folder, but Magisk would have said what and where on the patching screen when done
    10. In Odin flash this new AP file
    11. If needed reinstall Magisk app, open it and let it update

    To get saftey net to pass I had to use The universal saftey net magisk module found somewhere on this site. I can find it later if needed

    Those are the steps I did, hope it helps

    There seems to be no way to unlock the bootloader on the SM-A526U.
    Everything I tried fails.
    When you enable developer options on this model (SM-A526U) the unlock for the bootloader is non existent.

    You mean there is no unlock OEM option on your model?
    Correct, there is no OEM unlock option for the SM-A526U.

    Reading in to it who is your service provider? Is it T-Mobile? Regardless,it seems your phone needs to either be unlocked by them or a 3rd party. Or you can try to call them and convince them you need the OEM unlock button for work purposes.

    You have to activate the Magisk Hide option in the settings, then hide Health app and Health service.
    You may have to hide other app if you want other functionalities such as Secure Folder or others...

    Have a better look at your list as it should be there : Health Service and then Samsung Health.

    If Samsung Health is hidden, try to run it and to set it up and see if it works.
    Then get back to Magisk hide and see if the Health service is there.
